As to fuel efficiency, around 10-12 gph at 75%. Noise, different, but not much louder due to the turbo. Conversion costs, again, no idea. At this point, we have around $15,000 in the Rotary, including fabrication and dyno time. Accessories, maybe another $5-6K. Cowling is a work in progress, but it won't look like a stock Legacy when we're done.....(:-) Weight and balance should come out (hopefully) pretty close to stock. We will keep all posted as we proceed. Suffice to say the main attraction as I said earlier, was 4 total moving parts, higher hp to weight ratio, and running on pump gas, not to mention, cheap rebuild/maintenance costs.
